What is the hardest personality type?

So, let me ask you this - when it comes to personality types, which one would you say poses the greatest challenge? Is it the type that's overly cautious, constantly questioning every move and decision? Or perhaps it's the impulsive one, always jumping into things without considering the consequences? Could it be the stubborn individual who refuses to budge from their opinions, no matter how logical the alternative may be? Or maybe it's the indecisive type, struggling to make up their mind even on the simplest of matters. Each of these personality traits, in their own way, can make navigating personal and professional relationships quite difficult. But which one do you think truly stands out as the hardest to deal with?
